I've been pouring over studies and stats that seem to support this. Over 50% of men wil die by their 70th birthday due to the elevated rates of heart disease and cancer. A few will live into their 70s and 80s, and a very small few into their 90s, which brings the life expectancy up to 70.
Life expectancy does not mean "average of the death", and the latter is where you see the real difference.
The average age for death for a man is probably around 68, while for women its probably around 85.
Once a man hits 60 he has to worry about cancer and heart disease and dying, women are basically free from having to be overly concerned until about 80.

Is it true that most men die in their 60s, and most women in their 80s?
No, it's not true. "Most" means "more than half."
13 percent of males and 9 percent of females die in their sixties. Much less than half.
32 percent of males and 34 percent of females die in their eighties. That's less than half and not greatly different for the two sexes.
These numbers are for the United States in 2008. The source is given at the end of this answer.

Averages are the wrong conceptual tool for this kind of question. Here's a better way. Let's start by graphing the probability of dying for men and women at various ages.
(If probabilities seem confusing, multiply them by 100,000 and think of them as the number of people out of 100,000 who die every year.)
As you can see, there is no sudden increase in deaths for men in their sixties or women in their eighties. In fact, there are no large bumps anywhere. Both curves are pretty smooth.
What we do see is that at most ages, men are more likely than women to die. That greater likelihood appears on the graph as the gap between the two curves. That gap is what interests us. It represents the difference between the probability of dying for men and women. It's impossible to tell from this graph when the difference begins, but we can see that it increases smoothly up to a certain point and continues to exist at least until age 100.
The next step is to examine the difference more closely by graphing it. As you can see, the difference begins in adolescence, shows a slight bump in the early 20s, stays steady until the late 30s, and then rises fairly smoothly (although non-linearly) until the 90s. Contrary to your speculations, there is no change in the curve in the sixties or eighties, but there is a change in the early 90s.
(My guess about the bump in the early 20s is that it's caused mainly by male violence and risk-seeking behavior, not disease.)
Coffeesnob asked in comments whether the second graph above is statistically significant. It should be noted that these graphs don't show samples. They are based on an actual count of all the people who died in the US in a given year.
The gist of Coffeesnob's question is whether these graphs show real differences between men and women and not just a random fluke. Yes, they do. We know this because the same statistics for other years are almost identical. Here (below) are two more graphs that show the previous year. They are very similar to the graphs above.
The graphs for the two years are least similar at their far right ends. This may be due to the fact that the number of people is smallest there. The left sides of these graphs show enormous numbers of people. The larger the number of data points, the higher the accuracy of the result. Small differences can be statistically significant when the number of data points is large.

The numbers you post are pretty close to Estonia's. Is that where you're from?
Estonian men have a much more serious problem with alcohol than women, too. Bad livers might be the cause you're looking for.
There's probably no national epidemic of paleo dieting there.
